Hi guys,

this page needs to be updated: https://wiki2.dovecot.org/MailLocation/Maildir#Control_files

(link was from here: https://wiki2.dovecot.org/MailLocation)

Section 'Control files' is mentioning only 2 files but, in fact, Dovecot will store some additional files in CONTROL location: dovecot-uidvalidity dovecot-uidvalidity.*

This is already documented there.

subscriptions

This is controlled with 'SUBSCRIPTIONS' mail location setting, see https://wiki2.dovecot.org/MailLocation, it is not Maildir *specific* file.

(anything more?)

Even more, page https://wiki2.dovecot.org/MailLocation has missing note to CONTROL files location about storing files 'dovecot-uidlist' and 'dovecot-keywords' of INBOX inside .INBOX directory instead of root directory (as it's stored inside mailbox).

It's just not repeating the same thing. It says "location of control files" and links to Maildir

Missing anything from above will cause re-downloading of all e-mails by e-mail clients!

Except subscriptions.

And finally, i'm attaching a Python script which will safely copy/move CONTROL files from mail_location to new location (btw, moving it on SSD storage caused quite high performance boost in our environment).

Thanks.
